1. System Safety CAUTION : To prevent power surge and damage to the board, apply and remove power by the AC source of the power supply. DO NOT PLUG AND UNPLUG AT THE BOARD. CAUTION : To insure proper operation of the board be sure all wiring and connections are correct and secure. CAUTION : Keep fluids away from the electronics. CAUTION : To prevent heat buildup in the motor, current to the motor should be reduced to holding current or turned off between cycles. 2.
ACCESSORY OUTPUTS: Two dedicated power level outputs rated at supply voltage (24VDC) and 150 milliamps each are available to drive external solenoids or relays. TTL LEVEL INPUTS: Two dedicated TTL compatible high impedance, single ended, nonisolated, ground referenced, 5V inputs are provided. One is for Fluid Metering Inc. 5-wire optical sensor. The other is high speed input capable recognizing an input pulse with a duration as little as 4 Microseconds.
NOTES ON TTL LOGIC: For interface to PLC or other type of control. TTL (Logic High) ≥ 2.0 Vdc TTL ( logic Low) ≤ 0.6 Vdc Vin ( Absolute Maximum) = 5Vdc Vin ( Absolute Mininum) = 0.0Vdc Vin ( Logical High) = ≥ 3.5 Vdc. Vin ( Logical Low) = ≤ 1.0 Vdc. ACCEPTABLE INPUTS 5 Vdc DRY CONTACT OPEN COLLECTOR (OPEN DRAIN) TTL or CMOS LOGIC 4. Wiring Specifications 4.1 P/N ICST-01 Wiring for terminal strip marked J12: Number 1 is the B bar phase to the motor. Number 2 is the B phase to the motor.
Number 9 is the Dip Switch 6 (I/O6), the Blue wire. Number 10 is the Dip Switch 7 (I/O7), the White wire. 4.1 P/N ICST-01/ OEM J1 PIN # I/O Connector FUNCTION Pin 1 Pin 2 Pin 3 Pin 4 Pin 5 Pin 6 Pin 7 Pin 8 Pin 9 Pin 10 Pin 11 Pin 12 Pin 13 Pin 14 Ground the Lt Blue wire. Ground the Lt Blue wire.
5. Programs and Programming The “ICST” driver board is fully programmable and is designed to drive a low power stepper motor through a pre-configured profile while exercising discrete outputs and responding to inputs as necessary. The SCL (“Simplified Control Logic”) is a set of commands that allow stepper motor position and timing control to be preset into a non-volatile memory. Board retains program in memory after the board is powered down. Reapply power to the board and start the program.
Quick Start Screens: Level 1, called “Pick and Run”, is designed to allow the least experienced user to select a program from a list of documented programs, load that program into the hardware, and enable program execution. Some operational parameters may be optionally adjusted at this level. Level 2 – The “Target Inspector”, is designed for hardware checkout. On this level, an engineer can see the target hardware the way the SCL controller sees it.
Level 3 – This level “Building Blocks” is currently being developed. Level 4 – This area is reserved for the advanced SCL programmer. Full control over all features in the target is available to the user at this level. While SCL is considerably less demanding than other micro-controller programming languages, it still requires a level of “Logical” expertise that is better suited to someone with a programming background.
Pick and Run Screen: Single click on a program in list brings the program description into the description window for review prior to loading. Double click will auto load the program into the board processor. The program controls “Tweakable parameters”associated with the program are also shown. Target Inspector Screen: This screen shows boards I/O’s , This screen allows operator to check And verify the operation of the boards I/O functions.
Advance Program Screen: This screen by default opens with Project Description, Program List and Program Controls. Program List and Program controls can be closed by clicking on the “X” button. Use the mouse pointer to check the definitions of the icons each has a pop up definition. Two icons of note are the check and the bug. The check icon: Checks the program for errors. The bug icon: This brings up the Simulator/ Debugger screen. SEE THE NEXT SCREEN.

Operational: +20º c to +60º c. Mechanical: Circuit Board: Dimension: 3” [76,2 mm} X 3.75” [95,3 mm] X 1” [25,4 mm] Mounting: 4 Holes: Ø 0.
7. Trouble Shooting 1. Be sure all connections are tight and secure. 2. Be sure all wiring is to the wiring specifications. 3. Be sure power is applied, typical 24 Vdc @ 2 A, 30 Vdc max. 4. Board fails to respond, chips on the board get hot: The major cause for total board failure is hot swapping the power connector at the driver board this causes a power serge and may also cause static discharge. The board is static sensitive. 5.
